I never ran into this case, what is the status code returned by the http request?
If the status code is a 4xx or 5xx it implies something went wrong with the request and you can get this information in the ExceptionHandler.

Hi,
How do we get metadata(search_metadata) for search done using Search.SearchTweets(searchParameter). Is there any other way to do search with search metadata.
I am particularly interested in next_results and refresh_url metadata.
